ABSTRACT:
A flat panel display is coupled with an electrostatic stylus driven digitizing panel to produce a display and digitizer system having an interference control feature. The interference control feature first determines the operating frequency of the flat panel display and/or the operating frequency of the stylus. The interference controller may then incrementally reduce the operating frequency of the flat panel display and/or the operating frequency of the stylus until the operating frequency causing the least interference is ascertained. Once the operating frequency causing the least interference is ascertained the interference controller selects new operating parameters for the display and digitizer system.
